I use [Heraclitus' discovery of] enantiodromia for the emergence of the unconscious opposite in the course of time. This characteristic phenomenon practically always occurs when an extreme, onesided tendency dominates conscious life; in time an equally powerful counterposition is built up, which first inhibits the conscious performance and subsequently breaks through the conscious control.
Carl JungIt is really the mistake of our age. We think it is enough to discover new things, but we don't realize that knowing more demands a corยญresponding development of morality.
